 - **non_service_error**: "non"修饰的是“service_error"，后者即是分列在各个服务下的error，此外的error都计入non_service_error。服务处理过程中client断开连接导致无法成功写回response就算non_service_error。而服务内部对后端的连接断开属于服务内部逻辑，只要最终服务成功地返回了response，即使错误也是计入该服务的error，而不是non_service_error。

+Meaning of the fields above:
+
+- **non_service_error**: the count of errors except the ones raised by the services. For example, it is a *non_service_error* that the client closes connection when the service is processing requests since no response could be written back, while it counts in the *service error* when the connection established internally in the service is broken and the service fails to get reponse from the remote side.
+- **connection_count**: The number of connections to the server, excluded the ones connected to remote.
+- **example.EchoService**: Full name of the service, including the package name。
+- **Echo (EchoRequest) returns (EchoResponse)**: Signature of the method, a services can have multiple methods, click request/response and you can check out the corresponding protobuf message.
+- **count**: Number of requests that are succesfully processed.
+- **error**: Number of requests that meet failure.
+- **latency**: On the web page it shows average latency in the recent *60s/60m/24h/30d* from *right to left*. On plain text page it is the average latency in recent 10s(by default, specified by [-bvar_dump_interval](http://brpc.baidu.com:8765/flags/bvar_dump_interval).
+- **latency_percentiles**: The percentail of latency at 50%, 90%, 99%, 99.9% in 10 seconds(specified by[-bvar_dump_interval](http://brpc.baidu.com:8765/flags/bvar_dump_interval)），it shows adtional historical values on the web page.
+- **latency_cdf**: Anther view of percentiles like histogram，only available on web page.
+- **max_latency**: On the web page it shows the max latency in the recent *60s/60m/24h/30d* from *right to left*. On plain text page it is the max latency in recent 10s(by default, specified by [-bvar_dump_interval](http://brpc.baidu.com:8765/flags/bvar_dump_interval).
+- **qps**: On the web page it shows the qps in the recent *60s/60m/24h/30d* from *right to left*. On plain text page it is the qps in recent 10s(by default, specified by [-bvar_dump_interval](http://brpc.baidu.com:8765/flags/bvar_dump_interval).
